Name

scsi_hba_tran - SCSI Host Bus Adapter (HBA) driver transport vector structure

Synopsis

#include <sys/scsi/scsi.h>

Interface Level

Solaris architecture specific (Solaris DDI).

Description

A scsi_hba_tran_t structure defines vectors that an HBA driver exports to SCSA interfaces so that HBA specific functions can be executed.

Structure Members

tran_hba_dip
dev_info pointer to the HBA supplying the scsi_hba_tran structure.
tran_hba_private
Private pointer which the HBA driver can use to refer to the device’s soft state structure.
tran_tgt_private
Private pointer which the HBA can use to refer to per-target specific data. This field may only be used when the SCSI_HBA_TRAN_CLONE flag is specified in scsi_hba_attach(9F) . In this case, the HBA driver must initialize this field in its tran_tgt_init(9E) entry point.
tran_sd
pointer to scsi_device(9S) structure if cloning; otherwise NULL .
tran_tgt_init
is the function entry allowing per-target HBA initialization, if necessary.
tran_tgt_probe
is the function entry allowing per-target scsi_probe(9F) customization, if necessary.
tran_tgt_free
is the function entry allowing per-target HBA deallocation, if necessary.
tran_start
is the function entry that starts a SCSI command execution on the HBA hardware.
tran_reset
is the function entry that resets a SCSI bus or target device.
tran_abort
is the function entry that aborts one SCSI command, or all pending SCSI commands.
tran_getcap
is the function entry that retrieves a SCSI capability.
tran_setcap
is the function entry that sets a SCSI capability.
tran_init_pkt
is the function entry that allocates a scsi_pkt structure.
tran_destroy_pkt
is the function entry that frees a scsi_pkt structure allocated by tran_init_pkt.
tran_dmafree
is the function entry that frees DMA resources which were previously allocated by tran_init_pkt.
tran_sync_pkt
synchronize data in pkt after a data transfer has been completed.
tran_reset_notify
is the function entry allowing a target to register a bus reset notification request with the HBA driver.
